1879N/A * @bug 6224700
1879N/A * @summary ReferenceType.nestedTypes() is too slow
1879N/A * @author jjh
1879N/A *
1879N/A * @run build TestScaffold VMConnection TargetListener TargetAdapter
1879N/A * @run compile -g AnyDebuggeeTest.java
1879N/A * @run main AnyDebuggeeeTest
1879N/A *
0N/A * This test is intended to be run manually to investigate behaviors;
0N/A * it is not an actual test of any specific functionality, it just
0N/A * allows you to run the debugger part of this test on any debuggee.
1703N/A * As set up, it prints the time to find all nested types and all
1703N/A * subclasses in the debuggee, and so can be used to verify the
0N/A * fix for 6224700.
3863N/A *
0N/A * For other investigations, edit this test to do whatever you want.
0N/A * To run this test do this:
0N/A * runregress -no AnyDebuggeeTest <cmd line options>
0N/A * where <cmd line options> are the options to be used to
0N/A * launch the debuggee, with the classname prefixed with @@.
1703N/A * For example, this would run java2d demo as the debuggee:
0N/A * runregress -no AnyDebuggeeTest -classpath $jdkDir/demo/jfc/Java2D/Java2Demo.jar \
0N/A * -client @@java2d.Java2Demo'
1703N/A * If <cmd line options> is not specified, then the AnyDebuggeeTarg class below
0N/A * is run as the debuggee.
